From: Scaling law of real traffic jams under varying travel demand
Power law relationship of road congestion on March 1st in Shanghai. (A) A demonstration of cascading progress in the traffic network. Color represents the state of road segments, including spontaneous congestion (pink), cascading diffusion (red), existing congestion (orange), and dissipation (blue). (B) Power-law relationship between the total number of congested roads C and the travel demand V (represented by the number of vehicles recorded) in consecutive periods. (C) Illustration of the scaling relationship between the number of congested roads generated by diffusion, denoted as f and the total number of congested roads C. (D) Illustration of the scaling relationship between the number of spontaneously generated congested roads I and the total number of congested roads C. (E) Illustration of the scaling relationship between the number of dissipating roads R and the total number of congested roads C
